Abstract
Abstract A soft, lightweight toy for a child having an animal-like appearance and feeling warm to the touch of a child. The toy comprises a thin, flexible fabric cover defining a recess. A bladder containing a fluid is removably received in the recess and adapted to lie in contact with inner surfaces of the cover so as to provide a thin layer of the fluid adjacent inner surfaces of the cover. The bladder may be removed and warmed by various means to a desired temperature. Upon insertion into the recess, heat from the bladder is transferred through the cover making the toy warm to the touch. Apart from the thin layer of fluid encapsulated in the bladder under the inner surfaces of the cover, the toy comprises low density materials.

Claim 8
Dependent Claim
56 words
A toy as claimed in claim 4 wherein the plastic sheeting comprising the inner and outer walls are sealed together about their peripheries and at locations intermediate their peripheries spaced sufficiently closely so that with the bladder means filled with the first material, the first and second walls will only be spaced said relatively small distances.
Claim 9
Dependent Claim
34 words
A toy as claimed in claim 5 wherein the plastic sheeting comprising the inner and outer walls are sealed together to provide a plurality of individual sealed compartments filled with the fluid or gel.
Claim 10
Dependent Claim
21 words
A toy as claimed in claim 8 wherein the cover means comprises a thin layer of flexible heat transmitting woven fabric.
Claim 11
Dependent Claim
154 words
A toy as claimed in claim 7 wherein, the bladder means has a sheet-like configuration with the thickness between the inner and outer walls small compared to the width and length of the inner and outer walls, the bladder means adapted to be manually rolled into a coiled configuration, with the bladder means when coiled having an inherent bias to uncoil, access opening means permitting access through the cover means to the recess, the bladder means, recess and access opening means relatively sized and configured so that the bladder means when coiled can manually be inserted into the recess through the access opening means, located in the recess in a desired orientation and released; wherein upon release the bladder means uncoils under its bias to expand forcing the cover means outwardly to inflate the recess with the outer wall of the bladder means urged into contact with the inside surfaces of the cover means.
Claim 12
Dependent Claim
39 words
A toy as claimed in claim 10 wherein said bladder means includes elongate resiliently flexible members coupled thereto which become elastically deformed on coiling of the bladder means thereby impacting the inherent bias to the bladder means to uncoil.
Claim 13
Dependent Claim
